Sound Effects: Parker Solar Probe Passes Acoustic Testing

When NASA’s Parker Solar Probe lifts off on top of a Delta IV Heavy launch vehicle in summer 2018, it will undergo both intense vibration from the physical forces of the rocket engines, as well as acoustic effects from the sound of the engines and the rocket going through the atmosphere.

Verifying the spacecraft and its systems are ready for the rigors of launch is one of the most important parts of testing. On Nov. 3, Parker Solar Probe passed vibration testing at the Johns Hopkins Applied Physics Laboratory, or APL, in Laurel, Maryland, where it was designed and built. On Nov. 14, the spacecraft successfully completed acoustic testing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and is now being prepared for further environmental tests.
